Hello all, I wrote a python library ( (with minimal C extensions) that implements svg rendering using opengl, and it's designed with interaction as a main goal. It's a bit rough, but if somebody wants to try it, feel free to do so (bazaar-style): http://www.tls.cena.fr/~conversy/research/sauvage/ have fun. (btw, it's LGPL'ed.) don't hesitate to give me comments, and report problems, especially during compile. I developped it under macosx, but this time I did my best to make it compile under linux... stephane |

Well, I can't find that demo, but the only thing you need to know is "glShaderSourceARB" is a little different from spec. You can only load one program per call, where normally you could upload multiple at once. The code pretty much looks like C code otherwise. glShaderSourceARB(shaderObj, programString) - Charlie On Aug 21, 2005, at 8:25 AM, horace wrote: > hi, > > yes, i would like to see your example! i have never build something > from cvs before but i will try. :) > > so in future pyopengl releases your extensions will be in? > > thanks! > > On 8/21/05, Charles Moad <cm...@in...> wrote: > >> I committed all the necessary extension into cvs about a >> month ago to >> do glsl programming.

hi, yes, i would like to see your example! i have never build something from cvs before but i will try. :) so in future pyopengl releases your extensions will be in? thanks!

I committed all the necessary extension into cvs about a month ago to do glsl programming. You would have to build from cvs, and I may have a sample app sitting around somewhere.

hi, is it possible to use opengl extensions with pyopengl? i would like to do some experiments with shader programming and python+pyopengl would be perfect for that. is pyopengl still opengl 1.1 only? |

GL_COLOR_TABLE and glColorTable give me NameErrors. Where are they? (I'm using opengl 2.0) Thanks, Bum __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com |

Mike, Yes, what I had in mind was involved, but your idea is much better! We have more than one GL window in which things can be drawn; so we'll have to provide a setup call that can be invoked from within python which, among other things, will set the current window, buffer, etc. This main drawing area allows stereo (software pairs, hardware). It'd be nice to figure out a way to allow clients to write their code so it integrates with stereo in our main drawing Window. I don't think they will be able to get the needed information (like how much we rotate each eye's view) from the GL state machine; so we'll probably have to provide some additionall wrappes for this. Thanks for the help, Herc |

Hi, I'm working with support from the Python Software Foundation to develop an open source course on basic software development skills for people with backgrounds in science and engineering. I have a beta version of the course notes ready for review, and would like to pull in people in sci&eng to look it over and give me feedback. If you know anyone who fits this bill (particularly people who might be interested in following along with a trial run of the course this fall), I'd be grateful for pointers. Thanks, Greg Wilson |

From the docs for gluPickMatrix:
The matrix created by gluPickMatrix is multiplied by the current
matrix just as if glMultMatrix is called with the generated matrix.
To effectively use the generated pick matrix for picking, first call
glLoadIdentity to load an identity matrix onto the perspective
matrix stack. Then call gluPickMatrix, and finally, call a command
(such as gluPerspective) to multiply the perspective matrix by the
pick matrix.
which suggests you want the gluOrtho call *after* the gluPickMatrix
call. I don't actually recall reversing the order in *my* code, but
then I haven't written code of this type in a long while.

You are creating a rectangular prism centred around the pick location.
So, do 8 gluUnProjects, one for each corner of the prism, with the near
face having winz of 0.0 and the far face having winz of 1.0. That
should give you a rectangle in model-space coordinates that you can
render (if I'm working through the logic correctly).
btw, you might want to check around and see if bitmap operations where
the bitmap position is outside of the picking matrix actually register
with a selection buffer (i.e. they don't draw if the bitmap position is
out-of-frustum, do they select when outside the picking frustum?)
Anyway, HTH,
Mike

I'm trying to use glRenderMode(GL_SELECT) to implement picking. The
problem is, almost all picking examples deal with 3D projection
(gluPerspective), whereas I am using glOrtho, so I suspect I need to
do something different.
The below code doesn't work, it accumulates hits in the select buffer,
but they are not the hits I expect. Any pointers on where I might be
going wrong?
Also, is there a simple way to get OpenGL to render a small box on the
screen which shows exactly which region is being picked?
Thanks for any help...=20
Sw.
def pick(self, position):
glInitNames()
glSelectBuffer(64)
glRenderMode(GL_SELECT)
glMatrixMode(GL_PROJECTION)
glPushMatrix()
glLoadIdentity()
viewport =3D glGetIntegerv(GL_VIEWPORT)
n_w,n_h =3D display._screen.dimensions
glOrtho(-n_w,n_w,-n_h,n_h,1,0)
gluPickMatrix(position[0],viewport[3]-position[1],3,3,viewport)
glMatrixMode(GL_MODELVIEW)
for index, i in enumerate(self.items):
glPushName(index)
display._screen.blit(i.item, i.position)
glPopName()
glMatrixMode(GL_PROJECTION)
glPopMatrix()
glMatrixMode(GL_MODELVIEW)
glFlush() =20
items =3D []
for hit in glRenderMode(GL_RENDER):
items =3D items + [self.items[i] for i in hit[2]]
return items

I think you're missing what's returned from the glRenderMode code (which
is non-standard OpenGL, to avoid the need for Python code using and
decoding structured pointers), from OpenGLContext:
nameStack = list(glRenderMode(GL_RENDER))
that is, you get a stack of name records (i.e. your glSelectBuffer with
(near,far,names) records) back from the glRenderMode call, *not* just a
count of the records produced.
In general, you shouldn't *need* OpenGLContext to do anything, as all of
its OpenGL code is written directly in Python to PyOpenGL's API (that
was its original purpose in life, to test those APIs). It is, however,
intended to provide a source for sample code showing how to accomplish
effects when using PyOpenGL, so from renderpass.py:
event.setObjectPaths([
nodepath.NodePath(filter(None,[
self.selectable.get(name)
for name in names
]))
for (near,far,names) in nameStack
])
shows you how to deal with the glSelectBuffer result, namely that it's a
near value, a far value, and a set of integer names (the name stack) for
each record in the set. OpenGLContext is here creating a node-path of
all selectable objects from the scenegraph root to the final selected
object using the nameStack and a registered set of name:node values
(self.selectable). It will use those to populate the event objects that
show up in the OpenGLContext mouse-event-handling APIs.
HTH,
Mike

In your C++ code, set the current GL context, then call the PyOpenGL code. When you want to do a glx-level function, return control to your application, either by returning from your PyOpenGL function, or by providing a wrapped method to your code that calls whichever piece of code you want to trigger. PyOpenGL renders to the current rendering context of the process (as does all OpenGL), so you don't need to do anything special for connecting it to your widgets. The only time you need the special code is when you want to make the window manipulations themselves (glx calls) from Python. If you really do want the window manipulation to happen in Python, you can look at the source code for PyGame's GL widget, or the Togl source-code, which are just encapsulations of the platform APIs for use by Python (or TCL).

I have an application written in c++ and motif which draws into a 3D Workspace using OpenGL. I'd like to be able to use PyOpenGL to draw into this same window. To do this I need to be able to specify to PyOpenGL which window is the drawing window. I think I can manage to get the window/widget id back to python by providing some python accessor functions which will allow my python app to get this info. What is not clear to me is what function(s) would I call to set the buffer appropriately. Typically we call glXSwapBuffers in our c++ app, but I don't see any glx* functions in PyOpenGL. What module and/or functions can I use to do this? Any pointers, suggestions would be much appreciated. Herc |

Registration is now open for the first Python Game Programming Challenge (also known as PyWeek). The challenge runs from Sunday August 28th to Sunday September 4th. That means there's only (checks website) 29 days to go before the challenge starts! Full details about the challenge, and registration, at the website: http://www.mechanicalcat.net/tech/PyWeek/ You may enter either individually or as a team. If you're keen and would like to join a team, but can't organise your friends, then sign up anyway and offer your services to other entrants. The challenge will use skills in Python programming, graphics, sound or music. For those who came in late, the PyWeek challenge: 1. Invites entrants to create a game (coded in Python) in one week from scratch either as an individual or in a team, 2. Aims to be challenging and fun, 3. Entries must be developed during the competition, and must incorporate some theme decided at the start of the competition, 4. Will hopefully increase the public body of python game tools, code and expertise, 5. Will let a lot of people actually finish a game, and 6. May inspire new projects (with ready made teams!) -- Visit the PyWeek website: http://www.mechanicalcat.net/tech/PyWeek/ |

Sending this to the main list, as your personal e-mail isn't accepting my=20 messages for some reason. Anyway, I am using the Z buffer. Is that a problem? =A0=A0=A0=A0=A0=A0=A0=A0-Matt Bailey On Sunday 17 July 2005 20:54, Fred Burton set 1,000 monkies in front of=20 keyboards and came up with the following: > Are you using Z-Buffering ? |

Howdy all,
I just ran into something really weird (and incredibly annoying) with
textures and alpha channels. In my game, I've been using my own module to
load a 3D model from an ASCII file and load a texture for this object with
PIL (specifying the correct mode). The new object has an "update" function
that pushes the matrix, does any translations, binds the object's texture,
calls the object's display list, and pushes the matrix, thusly:
glPushMatrix()
glTranslate(self.x, self.y, self.z)
glBindTexture(GL_TEXTURE_2D, self.model.texture)
glCallList(self.model.displaylist)
glPopMatrix()
self.model is where the actual loading of the model and texture takes place,
and functions as a holder for these.
I have two basic types of objects.........one is a building, which uses a PNG
file with no alpha channel (so loading it from PIL, I use the 'RGBA' mode).
The other is my "ship", which uses alpha textures (RGBX mode). In the
initialization of the game, I first call my "ship" object, which contains an
update function essentially the same as the buildings object (aside from
translations, the actual per-cycle OpenGL code is 100% identical). I then
create some instances of the building object, with a non-alpha texture. I
create several instances of this object at various locations.
The problem is that my ship is not displaying with the alpha channel, it's
just solid 100% opacity. However, if, after loading the building objects on
initialization, I load another object with an alpha image/RGBX mode, the ship
displays with the alpha texture as it should! I don't even have to ever use
the new alpha object, all I have to do is load an object with an alpha
texture some time after loading all the non-alpha textured objects.
It's like the non-alpha textures "override" the alpha textures. Everything
works if I load an alpha object last during the initialization, but this sure
seems silly. I could also load my ship object last, but I want to know why
this is acting this way in the first place. The way I see it, there's no
connections between these two objects and OpenGL shouldn't care what the last
texture that it loaded was because the texture loading code starts from
scratch when loading the new texture. Any ideas?
-Matt Bailey
PS: Here's how I'm handling alpha vs non-alpha textures in my texture loader:
if mode == 'RGBX':
glTexImage2D(GL_TEXTURE_2D, 0, 3, ix, iy, 0, GL_RGBA, GL_UNSIGNED_BYTE,
image)
glBlendFunc(GL_ONE, GL_ZERO)
elif mode == 'RGBA':
glBlendFunc( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA )
glEnable(GL_BLEND)
glTexImage2D(GL_TEXTURE_2D, 0, 4, ix, iy, 0, GL_RGBA, GL_UNSIGNED_BYTE,
image)
As you can see, I'm making the same calls, just with different parameters, so
nothing should be left "turned on/off" from the last texture call. "image"
is an image loaded with PIL.

Well I finally was able to compile and install. I had to make a few changes to get it to work. First, to get past the error in my previous post, I had to change config/linux.cfg and modified: include_dirs=/usr/include:/usr/local/include:/usr/X11/include:/usr/X11R6/include to: include_dirs=/usr/local/include Then I got errors from src/interface/_GLUT.0014.inc. These errors were remedied by adding #include <GL/freeglut_ext.h> at line 2411 in src/interface/_GLUT.0014.inc. Finally, I got errors compiling Togl because togl.c and togl.h couldn't include tcl.h and tk.h. This was fixed by changing the include statements to: #include <tcl8.4/tcl.h> #include <tcl8.4/tk.h> So, after these changes it compiled with a lot of warnings and installed. I was able to import the OpenGL module from the python interpreter. Now I just need to write an application to see if it really works. Thanks, Tom |

Hi, I am trying to install PyOpenGL-2.0.2.01 from the release tarball. I run 'python setup.py install' and see the errors given below. I'm not too worried about the missing __init__.py files. I don't know why they are not there but it doesn't look like they are necessary to build PyOpenGL. Now, the compile errors below them starting with src/interface/GL.ARB._shader_objects.0001.inc:1399: error: parse error before "obj" seem to be the major problem. The line it complains about is the last one in the following code snippet: #include <GL/glext.h> #if !EXT_DEFINES_PROTO || !defined(GL_ARB_shader_objects) DECLARE_VOID_EXT(glDeleteObjectARB, (GLhandleARB obj), (obj)) The glext.h header file is in /usr/local/inlcude/GL and it contains a typedef for GLhandleARB so I don't understand where the error is coming from. There is also a glext.h in /usr/include/GL which, does not contain a typedef for GLhandleARB. However, according to the compile command the glext.h in /usr/local/include/GL should be found first. gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O3 -march=athlon-xp -Wall -Wstrict-prototypes -fPIC -DGLX_PLATFORM -I/usr/include -I/usr/local/include -I/usr/X11/include -I/usr/X11R6/include -I/usr/local/include/python2.4 -c src/interface/GL.ARB._shader_objects.c -o build/temp.linux-i686-2.4/src/interface/GL.ARB._shader_objects.o Here's my system and what's on it: Debian Sarge Python 2.4.1 swig 1.3.24-1 xlibmesa-gl 4.3.0.dfsg.1-1 Mesa 3D graphics library [XFree86] xlibmesa-gl-dev 4.3.0.dfsg.1-1 Mesa 3D graphics library development files [XFree86] xlibmesa-glu 4.3.0.dfsg.1-1 Mesa OpenGL utility library [XFree86] xlibmesa-glu-dev 4.3.0.dfsg.1-1 Mesa OpenGL utility library development files [XFree86] freeglut3 2.2.0-8 OpenGL Utility Toolkit freeglut3-dev 2.2.0-8 OpenGL Utility Toolkit development files libgle3 3.1.0-5 OpenGL tubing and extrusion library libglut3 3.7-25 the OpenGL Utility Toolkit libglut3-dev 3.7-25 development libraries and headers for GLUT I searched the archives and google and didn't find anybody with this particular compile problem.
